BACKGROUND OF THE INVENTION

The present invention comprises a new class of compounds useful in treating diseases, such as TNF-α, IL-1β, IL-6 and/or IL-8 mediated diseases and other maladies, such as pain, cancer, and diabetes. In particular, the compounds of the invention are useful for the prophylaxis and treatment of diseases or conditions involving inflammation. This invention also relates to intermediates and processes useful in the preparation of such compounds.

Interleukin-1 (IL-1) and Tumor Necrosis Factor α (TNF-α) are pro-inflammatory cytokines secreted by a variety of cells, including monocytes and macrophages, in response to many inflamatory stimuli (e.g., lipopolysacchride—LPS) or external cellular stress (e.g., osmotic shock and peroxide).

Elevated levels of TNF-α and/or IL-1 over basal levels have been implicated in mediating or exacerbating a number of disease states including rheumatoid arthritis; Pagets disesase; osteophorosis; multiple myeloma; uveititis; acute and chronic myelogenous leukemia; pancreatic β cell destruction; osteoarthritis; rheumatoid spondylitis; gouty arthritis; inflammatory bowel disease; adult respiratory distress syndrome (ARDS); psoriasis; Crohn's disease; allergic rhinitis; ulcerative colitis; anaphylaxis; contact dermatitis; asthma; muscle degeneration; cachexia; Reiter's syndrome; type I and type Ii diabetes; bone resorption diseases; graft vs. host reaction; ischemia reperfusion injury; atherosclerosis; brain trauma; multiple sclerosis; cerebral malaria; sepsis; septic shock; toxic shock syndrome; fever, and myalgias due to infection. HIV-1, HIV-2, HIV-3, cytomegalovirus (CMV), influenza, adenovirus, the herpes viruses (including HSV-1, HSV-2), and herpes zoster are also exacerbated by TNF-α.

It has been reported that TNF-α plays a role in head trauma, stroke, and ischemia. For instance, in animal models of head trauma (rat), TNF-α levels increased in the contused hemisphere (Shohami et al., J. Cereb. Blood Flow Metab. 14, 615 (1994)). In a rat model of ischemia wherein the middle cerebal artery was occluded, the levels of TNF-α mRNA of TNF-α increased (Feurstein et al., Neurosci. Lett. 164, 125 (1993)). Administration of TNF-α into the rat cortex has been reported to result insignificant neutrophil accumulation in capillaries an dadherence in small blood vessels. TNF-α promotes the infiltration of other cytokines (IL-1β, IL-6) and also chemokines, which promote neutrophil infiltration into the infarct area (Feurstein, Stroke 25, 1481 (1994)). TNF-α has also been implicated to play a role intype II diabetes (Endocrinol. 130, 43-52, 1992; and Endocrinol. 136, 1474-1481, 1995).

TNF-α appears to play a role in promoting certain viral life cycles and disease states associated with them. For instance, TNF-α secreted by monocytes induced elevated levels of HIV expression in a chronically infected T cell clone (Clouse et al., J. Immunol. 142, 431 (1989)). Lahdevirta et al., (Am. J. Med. 85, 289 (1988)) discussed the role of TNF-α in the HIV associated states of cachexia and muscle degradation.

TNF-α is upstream in the cytokine cascade of inflammation. As a result, elevated levels of TNF-α may lead to elevated levels of other inflammatory and proinflammatory cytokines, such as IL-1, IL-6, and IL-8.

Elevated levels of IL-1 over basal levels have been implicated in mediating or exacerbating a number of disease states including rheumatoid arthritis; osteoarthritis; rheumatoid spondylitis; gouty arthritis; inflammatory bowel disease; adult respiratory distress syndrom (ARDS); psoriasis; Crohn's disease; ulcerative colitis; anaphylaxis; muscle degeneration; cachexia; Reiter's syndrome; type I and type II diabetes; bone resorption diseases; ischemia reperfusion injury; atherosclerosis; brain trauma; multiple sclerosis; sepsis; septic shock; and toxic shock syndrome. Viruses sensitive to TNF-α inhibition, e.g., HIV-1, HIV-2, HIV-3, are also affected by IL-1.

TNF-α and IL-1 appear to play a role in pancreatic β cell destruction and diabetes. Pancreatic β cells produce insulin which helps mediate blood glucose homeostasis. Deterioration of pancreatic β cells often accompanies type I diabetes. Pancreatic β cell functional abnormalities may occur in patients with type II diabetes. Type II diabetes is characterized by a functional resistance to insulin. Further, type II diabetes is also often accompanied by elevated levels of plasma glucagon and increased rates of hepatic glucose production. GLucagon is a regulatory hormone that attenuates liver gluconeogenesis inhibition by insulin. Glucagon receptors have been found in the liver, kidney and adipose tissue. Thus glucagon antagonists are useful for attenuatingplasma glucose levels (WO 97/16442, incorporated herein by reference in its entirety). By antagonizing the glucagon receptors, it is thought that insulin responsiveness in the liver will improve, thereby decreasing gluconeogenesis and lowering the rate of hepatic glucose production.

In rheumatoid arthritis models in animals, multiple intr-articular injections of IL-1 have led to an acute and destructive form of arthritis (Chandrasekhar et al., Clinical Immunol Immunopathol. 55, 382 (1990)). In studies using cultured rheumatoid synovial cells, IL-1 is a more potent inducer of stromelysin than is TNF-α (Firestein, Am. J. Pathol. 140, 1309 (1992)). At sites of local injectin, netrophil, lymphocyte, and monocyte emigration has been observed. The emigration is attributed to the induction of chemokines (e.g., IL-8), and the up-regulation of adhesion molecules (Dinarello, Eur. Cytokine Netw. 5, 517-531 (1994)).

IL-1 also appearts to play a role in promoting certain viral life cycles. For example, cytokine-induced increase of HIV expression in a chronically infected macrophage line has been associated with a concomitant and selective increase in IL-1 production (Folks et al., J. Immunol. 136, 4049 (1986)). Beutler et al. (J. Immunol. 135, 3969 (1985)) discussed the role of IL-1 in cachexia. Baracos et al. (New Eng. J. Med. 308, 553 (1983)) discussed the role of IL-1 in muscle degeneration.

In rheumatoid arthritis, both IL-1 and TNF-α induce synoviocytes and chondrocytes to produce collagenase and neutral proteases, which leads to tissue destruction witin the arthritic joints. In a model of arthritis (collagen-induced arthritis (CIA) in rats and mice), intra-articular administration of TNF-α either prior to or after the inductin of CIA led to an accelerated onset of arthritis and a more severe course of the disease (Brahn et al., Lymphokine Cytokine Res. 11, 253 (1992); and Cooper, Clin. Exp. Immunol. 898, 244 (1992)).

IL-8 has been implicated in exacerbating and/or causing many disease states in which massive neutrophil infilttration into sites of inflammatin or injury (e.g., ischemia) is mediated by the chemotactic nature of IL-8, including, but not limited to, the following: asthma, inflamatory bowel disease, psoriasis, adult respiratory distress syndrome, cardiac and renal reperfusion injury, thrombosis and glomerulonephritis. In addition to the chemotaxis effect on neutrophils. IL-8 also has the ability to activate neutrophils. Thus, reduction in IL-8 levels may lead to diminished neutrophil infiltration.

Several approaches have been taken to block the effect of TNF-α. One approach involves using soluble receptors for TNF-α (e.g., TNFR-55 or TNFR-75), which have demonstrated efficacy in animal models of TNF-α-mediated disease states. A second approach to neutralizing TNF-α using a monoclonal antibody specific to TNF-α, cA2, has demonstrated improvement in swollen joint count in a Phase II human trial of rheumatoid arthritis (Maini et al., Immunological Reviews, pp. 195-223 (1995)). These approaches block the effects of TNF-α and IL-1 by either protein sequestration or receptor antagonism.

The present invention also relates to a method of treating cancer which is mediated by Raf and Raf-inducible proteins. Raf proteins are kinases activated in response to extracellular mitogenic stimuli such as PDG, EGF, acidic FDF, thrombin, insulin or endothelin, and also in response to oncoproteins such as v-src, v-sis, and v-fms. Raf functions downstream of ras in signal transduction from the cellular membrane to the nucleus. Compounds in the present invention may be oncolytics through the antogonism of Raf kinase. Antisense constructs which reduce cellular levels of c-Raf and hence Raf activity inhibit the growth of rodent fibroblasts in soft agar, while exhibiting little or no general cytotoxicity. This inhibition of growth in soft agar is highly predictive of tumor responsiveness in whole animals. Moreover Raf antisense constructs have shown efficacy in reducing tumor burden in animals. Examples of cancers where Raf kinase is implicated by overexpression include cancers of the brain, larynx, lung, lymphatic system, urinary tract and stomach, including hystocytic lymphoma, lung adenocarcinoma and small cell lung cancers. Other examples include cancers involving overexpression of upstream activators of Raf or Raf-activating oncogenes, including pancreatic and breast carcinoma.

Methods of preparation of these amine derivatives from corresponding amino acids, amino acid amides or amino acid esters are also well known to those skilled in the art of organic chemistry including amino acid/amino acid ester or aminoalcohol chemistry.

Protecting groups are removed under conditions which will not affect the remaining portion of the molecule. These methods are well known in the art and include acid hydrolysis, hydrogenolysis and the like. A preferred method involves removal of a protecting group, such as removal of a benzyloxycarbonyl group by hydrogenolysis utilizing palladium on carbon in a suitable solvent system such as an alcohol, acetic acid, and the like or mixtures thereof. A t-butoxycarbonyl protecting group can be removed utilizing an inorganic or organic acid, such as HCl or trifluoroacetic acid, in a suitable solvent system, such as dioxane or methylene chloride. The resulting amino salt can readily be neutralized to yield the free amine. Carboxy protecting group, such as methyl, ethyl, benzyl, tert-butyl, 4-methoxyphenylmethyl and the like, can be removed under hydrolysis and hydrogenolysis conditions well known to those skilled in the art.

Reduction of the nitro group can be performed by treatment of (3) with hydrogen gas in the presence of palladium on carbon or Raney nickel, or alternatively, by treatment with SnCl₂ in an alcoholic solvent and in the presence or absence of HCl to obtain 2-substituted-5-aminopyridines (4). The aminopyridines (4) may be alkylated using alkylhalides and an appropriate base or by reductive alkylation employing the appropriate aldehyde or ketone in the presence of a reducing agent, such as sodium triacetoxy borohydride, borane•THF and the like, to form the substituted aminopyridines (5). Either (4) or (5) may be acylated with an appropriate acid halide (e.g., R³C(O)Cl or R³C(O)Br) in the presence of a base, such as pyridine, DMAP and the like, or alternatively may be acylated with an anhydride, either mixed or symmetrical, or alternatively may be acylated by treatment with the appropriate acid (R³CO₂H) in the presence of a coupling agent such as a carbodiimide reagent to form the final product (1). Alternatively, substituted 2-bromo-5-nitropyridine analogs may be reduced to, substituted 2-bromo-5-aminopyridine analogs by the action of SnBr₂ in methanolic solvent. Subsequent acylation with an appropriate activated ester (i.e.: R³CO₂H in the presence of diisopropylcarbodiimide in methylene chloride as solvent) produces 2-bromopyridine-5-carboxamide compounds of structure (5a). Coupling of (5a) with an appropriate phenol in the presence of Cu(Ac)₂ and K₂CO₃ in DMF at 140° C. provides compounds of formula (1) where X═O.

6-Substituted-2-halo-5-nitro-pyridine analogs (6) may be prepared from 2,6-dichloro-5-nitropyridine according to the methods outlined in Scheme II. Treatment with one equivalent of an appropriate nucleophile of R⁷ or a precursor thereof (such as, HO⁻, RO⁻, AcS⁻, NC⁻, RS⁻ and the like) provides (6). Subsequent reaction to form (7) (treatment with R¹—X—H in the presence of base or Cu(I) in an appropriate solvent, such as THF, DMF, DME, DMSO and the like, at a temperature from −20° C. to 120° C.) and (8) (reduction of the nitro group and substitution with R⁴) is as described in Scheme I (cf. Colbry, N. L. et al.; J. Heterocyclic Chem., 21: 1521-1525 (1984); Matsumoto, Jun-ichi, et al.; J. Heterocyclic Chem., 21: 673-679 (1984)). (8) may be reacted with an acid halide or an activated

ester as shown in Scheme I to provide compounds of formula (1). Where R⁷═CN, compounds of formula (8) may be hydrolyzed to acids (R⁷═CO₂H) of formula (9) using acidic media such as HBr and the like. Utilizing the appropriate N-protecting groups, acids of formula (9) may be transformed into esters, amides and alcohols. Compounds of formula (9) and derivatives described above may be be reacted with an acid halide or an activated ester as shown in Scheme I to provide compounds of formula (1). compounds of formula (8), where R⁷═−CN, may be reduced to the primary amine (R⁷═−CH₂NH₂) using reagents such as BH₃ or hydrogen gas in the presence of palladium on carbon or Raney nickel. Subsequent manipulation and reaction of the primary amine may be performed in the presence of the pyridine-5-amine substituent due to it's greater reactivity. Specifically, compounds of formula (8) where R⁷═−CH₂NH₂ may be alkylated by treatment with an appropriate aldehyde or ketone in the presence of a reducing agent, such as sodium triacetoxy borohydride, or may be acylated by treatment with an appropriate activated ester, chloroformate, isocyanate and the like, or may be sulfonylated by treatment with an appropriate sulfonyl halide. Alternatively, substituted 3-aminopyridine intermediates may be prepared from the corresponding nicotinamide compound using Hofmann's reaction.

when R⁶ and/or R⁷ is an alkyl group, such as methyl, in compound (7), containing the appropriate protecting groups of or avoiding the presence of base sensitive groups, can be treated with strong base such as NaNH₂, PhLi, NaH or the like at temperatures from −78° C. to 22° C. then treated with electrophiles, such as alkyl halides, aldehydes, ketones and the like (cf. Fuerst, Feustel; CHEMTECH; 10: 693-699 (1958); Nishigaki, S. et al.; Chem. Pharm. Bull.; 17: 1827-1831 (1969); Kaiser, Edwin M.; Tetrahedron; 39: 2055-2064 (1983)). Alternatively, the alkyl group may be halogenated and the haloalkyl group may be reacted with a nucleophile, such as an amino group, alkoxy, alkylthiol and the like.

6-Chloronicotinoyl chloride analogs (10) are treated with the appropriate amine (R³R⁴NH) in the presence of base in an appropriate solvent, such as dichloromethane, acetonitrile, DMF, THF and the like, at a temperature from −20° C. to 120° C. to form nicotinamides (11) as shown in Scheme III. Alternatively, 6-chloronicotinic acid analogs (12) may be coupled with the appropriate amine via an anhydride, either mixed or symmetrical, or alternatively by treatment with the appropriate amine in the presence of a coupling agent such as a carbodiimide reagent to form the amide (11) 6-Chloronicotinamide analogs (11) are treated with the appropriate R¹—X—H in the presence of absence of base, or Cu(I) in an appropriate solvent, such as pyridine, ethylene glycol, DMF, DME, DMSO and the like, at a temperature from −20° C. to 180° C. to form the final product (13).

Substituted halopyridines may be readily prepared from the corresponding pyridones using phosphorus oxychloride or pentachloride.

Prodrugs of the compounds of this invention are also contemplated by this invention. A prodrug is an active or inactive compound that is modified chemically through in vivo physicological action, such as hydrolysis, metabolism and the like, into a compound of this invention following administration of the prodrug to a patient. The suitability and techniques involved in making and using prodrugs are well known by those skilled in the art. For a general discussion of prodrugs involving esters see Svensson and Tunek Drug Metabolism Reviews 165 (1988) and Bundgaard Design of Prodrugs, Elsevier (1985). Examples of a masked carboxylate anion include a variety of esters, such as alkyl (for example, methyl, ethyl), cycloalkyl (for example, cyclohexyl), aralkyl (for example, benzyl, p-methoxybenzyl), and alkylcarbonyloxyalkyl (for example, pivaloyloxymethyl). amines have been masked as arylcarbonyloxymethyl substituted derivatives which are cleaved by esterases in vivo releasing the free drug and formaldehyde (Bungaard J. Med. Chem. 21503 (1989)). Also, drugs containing an acidic NH group, such as imidazole, imide, indole and the like, have been masked with N-acyloxymethyl groups (Bundgaard Design of Prodrugs, Elsevier (1985)). Hydroxy groups have been masked as esters and ethers. EP 039,051 (Sloan and Little, Apr. 11, 1981) discloses Mannich-base hydroxamic acid prodrugs, their preparation and use.

General Procedure for the Synthesis of 6-(substituted-amino)-N-substituted nicotinamides

Step A. General procedure for the preparation of 6-chloro-N-substituted nicotinamide:

To a suspension of 6-chloronicotinoyl chloride (1.76 g, 10.0 mmol) in dry dichloromethane (10 mL) was added the amine (R³R⁴NH) (10.0 mmol) followed by the dropwise addition of triethylamine (1.7 mL, 12.2 mmol). After stirring for 40 min. at room temperature, the mixture was diluted with dichloromethane, washed with aqueous 1 M hydrochloric acid, saturated aqueous sodium hydrogencarbonate and water, dried over sodium sulfate and concentrated to dryness under reduce pressure to afford the desired nicotinamide.

The following compounds were prepared according to this procedure using the appropriate substituted amine:

6-Chloro-N-o-tolylnicotinamide: MS (m/z): 247/249 (M+H)⁺; C₁₃H₁₁Cl₁N₂O₁ requires 246.5.

6-Chloro-N-(2-fluorophenyl)nicotinamide: MS (m/z): 251/253 (M+H)⁺; C₁₂H₈Cl₁F₁N₂O₁ requires 250.7.

N-Benzyl-6-chloronicotinamide: MS (m/z): 247/249 (M+H)⁺; C₁₃H₁₁Cl₁N₂O₁ requires 246.7.

Step B. General procedure for the preparation of 6-(substituted-amino)-N-substituted nicotinamides

A mixture of the 6-chloro-N-substituted nicotinamide (12.5 mmol) and amine (R¹NH₂ or R¹NHCH₃) (20 mmol) in ethylene glycol (50 mL) or pyridine (alkylamines) (50 mL) was heated to 140° C. for 20 hours. After cooling to room temperature, the mixture was diluted with dichloromethane/methanol (9:1, 250 mL) and filtered through a plug of silica gel, washing with additional dichloromethane/methanol (9:1, 250 mL). Concentration under reduced pressure afforded the desired 6-(substituted-amino)-N-substituted nicotinamide.

The compounds listed in Tables 8-11 were prepared from 6-chloro-N-substituted nicotinamides compounds and the appropriate amine according to the general procedure above.

Lipopolysaccharide-activated monocyte TNF production assay

Isolation of monocytes

Test compounds were evaluated in vitro for the ability to inhibit the production of tumor necrosis factor (TNF) by monocytes activated with bacterial lipopolysaccharide (LPS). Fresh residual source leukocytes (a byproduct of plateletpheresis) were obtained from a local blood bank, and peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation on Ficol-Paque Plus (Pharmacia). PBMCs were suspended at 2×10⁶/ml in DMEM supplemented to contain 2% FCS, 10 mM, 0.3 mg/ml glutamate, 100 U/ml penicillin G and 100 mg/ml streptomycin sulfate (complete media). Cells were plated into Falcon flat bottom, 96 well culture plates (200 μl/well) and cultured overnight at 37° C. and 6% CO₂. Non-adherent cells were removed by washing with 200 μl/well of fresh medium. Wells containing adherent cells (˜70% monocytes) were replenished with 100 μl of fresh medium.

Preparation of test compound stock solutions

Test compounds were dissolved in DMSO. Compound stock solutions were prepared to an initial concentration of 10-50 μM. Stocks were diluted initially to 20-200 μM in complete media. Nine two-fold serial dilutions of each compound were then prepared in complete medium.

Treatment of cells with test compounds and activation of TNF production with lipopolysaccharide

One hundred microliters of each test compound dilution were added to microtiter wells containing adherent monocytes and 100 μl complete medium. Monocytes were cultured with test compounds for 60 min at which time 25 μl of complete medium containing 30 ng/ml lipopolysaccharide from E. coli K532 were added to each well. Cells were cultured an additional 4 hrs. Culture supernatants were then removed and TNF presence in the supernatants was quantified using an ELISA.

TNF ELISA

Flat bottom, 96 well Corning High Binding ELISA plates were coated overnight (4° C.) with 150 μL/well of 3 μg/ml murine anti-human TNF-α MAb (R&D Systems #MAB210). Wells were then blocked for 1 hr at room temperature with 200 μL/well of CaCl₂-free ELISA buffer supplemented to contain 20 mg/ml BSA (standard ELISA buffer: 20 mM, 150 mM NaCl, 2 mM CaCl₂, 0.15 mM thimerosal, pH 7.4). Plates were washed and replenished with 100 μl of test supernatants (diluted 1:3) or standards. Standards consisted of eleven 1.5-fold serial dilutions from a stock of 1 ng/ml recombinant human TNF (R&D Systems). Plates were incubated at room temperature for 1 hr on orbital shaker (300 rpm), washed and replenished with 100 μl/well of 0.5 μg/ml goat anti-human TNF-α (R&D systems #AB-210-NA) biotinylated at a 4:1 ratio. Plates were incubated for 40 min, washed and replenished with 100 μl/well of alkaline phosphatase-conjugated streptavidin (Jackson ImmunoResearch #016-050-084) at 0.02 μg/ml. Plates were incubated 30 min, washed and replenished with 200 μl/well of 1 mg/ml of p-nitrophenyl phosphate. After 30 min, plates were read at 405 nm on a V_(max) plate reader.

Data analysis

Standard curve data were fit to a second order polynomial and unknown TNF-α concentrations determined from their OD by solving this equation for concentration. TNF concentrations were then plotted vs. test compound concentration using a second order polynomial. This equation was then used to calculate the concentration of test compounds causing a 50% reduction in TNF production.

Compounds of the invention can also be shown to inhibit LPS-induced release of IL-1β, IL-6 and/or IL-8 from monocytes by measuring concentrations of IL-1β, IL-6 and/or IL-8 by methods well known to those skilled in the art. In a similar manner to the above described assay involving the LPS induced release of TNF-α from monocytes, compounds of this invention can also be shown to inhibit LPS induced release of IL-1β, IL-6 and/or IL-8 from monocytes by measuring concentrations of IL-1β, IL-6 and/or IL-8 by methods well known to those skilled in the art. Thus, the compounds of the invention may lower elevated levels of TNF-β, IL-1, IL-6, and IL-8 levels. Reducing elevated levels of these inflammatory cytokines to basal levels or below is favorable in controlling, slowing progression, and alleviating many disease states. All of the compounds are useful in the methods of treating disease states in which TNF-α, IL-1β, IL-6, and IL-8 play a role to the full extent of the definition of TNF-α-mediated diseases described herein.

Inhibition of LPS-Induced TNF-α production in mice

Male DBA/1LACJ mice are dosed with vehicle or test compounds in a vehicle (the vehicle consisting of 0.5% tragacanth in 0.03 N HCl) 30 minutes prior to lipopolysaccharide (2 mg/kg, I.V.) injection. Ninety minutes after LPS injection, blood are collected and the serum is analyzed by ELISA for TNF levels.

Selected compounds from the class have shown in vivo activity in a LPS mouse model in which serum levels of TNF-α were reduced in the presence of compounds of this invention.

Compounds of the invention may be shown to have anti-inflammatory properties in animal models of inflammation, including carageenan paw edema, collagen induced arthritis and adjuvant arthritis, such as the carageenan paw edema model (C. A. Winter et al Proc. Soc. Exp. Biol. Med. (1962) vol 111, p 544; K. F. Swingle, in R. A. Scherrer and M. W. Whitehouse, Eds., Antiinflammatory Agents, Chemistry and Pharmacology, Vol. 13-II, Academic, New York, 1974, p. 33) and collagen induced arthritis (D. E. Trentham et al J. Exp. Med. (1977) vol. 146, p 857; J. S. Courtenay, Nature (New Biol.) (1980), Vol 283, p 666).

Harvesting of CHO/hGLUR Cells for Assay

1. Remove media from confluent flask then rinse once each with PBS (Ca, Mg-free) and Enzyme-free Dissociation Fluid (Specialty Media, Inc.).

2. Add 10 ml Enzyme-free Dissoc. Fluid and hold for about 4 min. at 37° C.

3. Gently tap cells free, triturate, take aliquot for counting and centrifuge remainder for 5 min. at 1000 rpm.

4. Resuspend pellet in Assay Buffer at 75000 cells per 100 μl.

Membrane preparations of CHO/hGLUR cells can be used in place of whole cells at the same assay volume. Final protein concentration of a membrane preparation is determined on a per batch basis.

Assay

The determination of inhibition of glucagon binding can be carried out by measuring the reduction of I¹²⁵-glucagon binding in the presence of compounds of Formula I. The reagents are combined in 120 μL of assay buffer as follows:

Compound/ 250 μM ¹²⁵I- CHO/hGLUR Vehicle Glucagon Glucagon Cells Total  —/5 μl — 25 μl 100 μl Binding + 5 μl/—  — 25 μl 100 μl Compound Nonspecific  —/5 μl 1 μl 25 μl 100 μl Binding

The mixture is incubated for 60 min. at 22° C. on a shaker at 275 rpm. The mixture is filtered over pre-soaked (0.5% polyethylimine (PEI)) GF/C filtermat using an Innotech Harvester or Tomtec Harvester with four washes of ice-cold 20 mM Tris buffer (pH 7.8). The radioactivity in the filters is determined by a gamma-scintillation counter.

Thus, compounds of the invention may also be shown to inhibit the binding of glucagon to glucagon receptors.

Cyclooxygenase Enzyme Activity Assay

The human monocytic leukemia cell line, THP-1, differentiated by exposure to phorbol esters expresses only COX-1; the human osteosarcoma cell line 143B expresses predominantly COX-2. THP-1 cells are routinely cultured in RPMI complete media supplemented with 10% FBS and human osteosarcoma cells (HOSC) are cultured in minimal essential media supplemented with 10% fetal bovine serum (MEM-10% FBS); all cell incubations are at 37° C. in a humidified environment containing 5% CO₂.

COX-1 Assay

In preparation for the COX-1 assay, THP-1 cells are grown to confluency, split 1:3 into RPMI containing 2% FBS and 10 mM phorbol 12-myristate 13-acetate (TPA), and incubated for 48 hours on a shaker to prevent attachment. Cells are pelleted and resuspended in Hank's Buffered Saline (HBS) at a concentration of 2.5×10⁶ cells/mL and plated in 96-well culture plates at a density of 5×10⁵ cells/mL. Test compounds are diluted in HBS and added to the desired final concentration and the cells are incubated for an additional 4 hours. Arachidonic acid is added to a final concentration of 30 mM, the cells incubated for 20 minutes at 37° C., and enzyme activity determined as described below.

COX-2 Assay

For the COX-2 assay, subconfluent HOSC are trypsinized and resuspended at 3×10⁶ cells/mL in MEM-FBS containing 1 ng human IL-1b/mL, plated in 96-well tissue culture plates at a density of 3×10⁴ cells per well, incubated on a shaker for 1 hour to evenly distribute cells, followed by an additional 2 hour static incubation to allow attachment. The media is then replaced with MEM containing 2% FBS (MEM-2% FBS) and 1 ng human IL-1b/mL, and the cells incubated for 18-22 hours. Following replacement of media with 190 mL MEM, 10 mL of test compound diluted in HBS is added to achieve the desired concentration and the cells incubated for 4 hours. The supernatants are removed and replaced with MEM containing 30 mM arachidonic acid, the cells incubated for 20 minutes at 37° C., and enzyme activity determined as described below.

COX Activity Determined

After incubation with arachidonic acid, the reactions are stopped by the addition of 1 N HCl, followed by neutralization with 1 N NaOH and centrifugation to pellet cell debris. Cyclooxygenase enzyme activity in both HOSC and THP-1 cell supernatants is determined by measuring the concentration of PGE₂ using a commercially available ELISA (Neogen #404110). A standard curve of PGE₂ is used for calibration, and commercially available COX-1 and COX-2 inhibitors are included as standard controls.

The following compound exhibits activities in the Cyclooxygenase assay with IC₅₀ values of 10 μM or less: 2-(2,4-dimethylphenylamino)-5-(2,6-dichlorophenylcarbonyl amino)pyridine.

Raf Kinase assay

In vitro Raf kinase activity is measured by the extent of phosphorylation of the substrate MEK (Map kinase/ERK kinase) by activated Raf kinase. Phosphorylated MEK is trapped on a filter and incorporation of radiolabeled phosphate is quantified by scintillation counting.

MATERIALS

Activated Raf is produced by triple transfection of Sf9 cells with baculoviruses expressing “Glu-Glu”-epitope tagged Raf,val¹²-H-Ras, and Lck. The “Glu-Glu”-epitope, Glu-Try-Met-Pro-Met-Glu, was fused to the carboxy-terminus of full length c-Raf.

Catalytically inactive MEK (K97A mutation) is produced in Sf9 cells transfected with a baculovirus expressing c-terminus “Glu-Glu” epitope-tagged K97A MEK1.

Anti “Glu-Glu” antibody was purified from cells grown as described in: Grussenmeyer, et al., Proceedings of the National Academy of Science, U.S.A. pp 7952-7954, 1985.

Column buffer: 20 mM Tris pH=8, 100 mM NaCl, 1 mM EDTA, 2.5 mM EGTA, 10 mM MgCl₂, 2 mM DTT, 0.4 mM AEBSF, 0.1% n-octylglucopyranoside, 1 nM okadeic acid, and 10 μg/mL each of benzamidine, leupeptin, pepstatin, and aprotinin.

5x Reaction buffer: 125 mM HEPES pH=8, 25 mM MgCl₂, 5 mM EDTA, 5 mM Na₃VO₄, 100 μg/mL BSA.

Enzyme dilution buffer: 25 mM HEPES pH=8, 1 mM EDTA, 1 mM Na₃VO₄, 400 μg/mL BSA.

Stop solution: 100 mM EDTA, 80 mM sodium pyrophosphate.

Filter plates: Milipore multiscreen # SE3MO78E3, Immobilon-P (PVDF).

METHODS

Protein purification: Sf9 cells were infected with baculovirus and grown as described in Williams et al., Proceedings of the National Academy of Science, U.S.A. pp 2922-2926, 1992. All subsequent steps were preformed on ice or at 4° C. Cells were pelleted and lysed by sonication in column buffer. Lysates were spun at 17,000×g for 20 min, followed by 0.22 μm filtration. Epitope tagged proteins were purified by chromatography over GammaBind Plus affinity column to which the “Glu-Glu” antibody was coupled. Proteins were loaded on the column followed by sequential washes with two column volumes of column buffer, and eluted with 50 μg/mL Glu-Tyr-Met-Pro-Met-Glu in column buffer.

Raf kinase assay: Test compounds were evaluated using ten 3-fold serial dilutions starting at 10-100 μM. 10 μL of the test inhibitor or control, dissolved in 10% DMSO, was added to the assay plate followed by the addition of 30 μL of the a mixture containing 10 μL 5x reaction buffer, 1 mM ³³P-γ-ATP (20 μCi/mL), 0.5 μL MEK (2.5 mg/mL), 1 μL 50 mM β-mercaptoethanol. The reaction was started by the addition of 10 μL of enzyme dilution buffer containing 1 mM DTT and an amount of activated Raf that produces linear kinetics over the reaction time course. The reaction was mixed and incubated at room temperature for 90 min. and stopped by the addition of 50 μL stop solution. 90 μL aliquots of this stopped solution were transferred onto GFP-30 cellulose microtiter filter plates (Polyfiltronics), the filter plates washed in four well volumes of 5% phosphoric acid, allowed to dry, and then replenished with 25 μl scintillation cocktail. The plates were counted for ³³P gamma emission using a TopCount Scintillation Reader.

In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents. Tablets and pills can additionally be prepared with enteric coatings.

Liquid dosage forms for oral administration may include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents commonly used in the art, such as water. Such compositions may also comprise adjuvants, such as wetting, sweetening, flavoring, and perfuming agents.

Compounds of the present invention can possess one or more asymmetric carbon atoms and are thus capable of existing in the form of optical isomers as well as in the form of racemic or non-racemic mixtures thereof. The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, e.g., by formation of diastereoisomeric salts, by treatment with an optically active acid or base. Examples of appropriate acids are tartaric, diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric, and camphorsulfonic acid and then separation of the mixture of diastereoisomers by crystallization followed by liberation of the optically active bases from these salts. A different process for separation of optical isomers involves the use of a chiral chromatography column optimally chosen to maximize the separation of the enantiomers. Still another available method involves synthesis of covalent diastereoisomeric molecules by reacting compounds of the invention with an optically pure acid in an activated form or an optically pure isocyanate. The synthesized diastereoisomers can be separated by conventional means such as chromatography, distillation, crystallization or sublimation, and then hydrolyzed to deliver the enantiomerically pure compound. The optically active compounds of the invention can likewise be obtained by using active starting materials. These isomers may be in the form of a free acid, a free base, an ester or a salt.

The compounds of the present invention can be used in the form of salts derived from inorganic or organic acids. The salts include, but are not limited to, the following: acetate, adipate, alginate, citrate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, camphorate, camphorsulfonate, digluconate, cyclopentanepropionate, dodecylsulfate, ethanesulfonate, glucoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, fumarate, hydrochloride, hydrobromide, hydroiodide, 2-hyroxy-ethanesulfonate, lactate, maleate, methansulfonate, nicotinate, 2-naphthalenesulfonate, oxalate, palmoate, pectinate, persulfate, 2-phenylpropionate, picrate, pivalate, propionate, succinate, tartrate, thiocyanate, tosylate, mesylate, and undecanoate. Also, the basic nitrogen-containing groups can be quaternized with such agents as lower alkyl halides, such as methyl, ethyl, propyl, and butyl chloride, bromides and iodides; dialkyl sulfates, like dimethyl, diethyl, dibutyl, and diamyl sulfates, long chain halides such as decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides, aralkyl halides like benzyl and phenethyl bromides, and others. Water or oil-soluble or dispersible products are thereby obtained.

Examples of acids that may be employed to from pharmaceutically acceptable acid addition salts include such inorganic acids as hydrochloric acid, sulphuric acid and phosphoric acid and such organic acids as oxalic acid, maleic acid, succinic acid and citric acid. Other examples include salts with alkali metals or alkaline earth metals, such as sodium, potassium, calcium or magnesium or with organic bases.

While the compounds of the invention can be administered as the sole active pharmaceutical agent, they can also be used in combination with one or more compounds of the invention or other agents. When administered as a combination, the therapeutic agents can be formulated as separate compositions that are given at the same time or different times, or the therapeutic agents can be given as a single composition.
